In such an example, the control member 94 may either turn off or prevent the middle and upper conveyors belts 58, 60 from rotating while not in use or the control member 94 may rotate the middle and upper conveyor belts 58, 60, but they are not used in this cooking operation.

In another example, all three of the conveyor belts 56, 58, 60 may be used to cook food products within the cooking device 20. In this example, the cooking device 20 includes a second or upper inlet 98 in which food product may be introduced into the cooking device 20. This second inlet 98 is aligned with an inlet 100 of the upper conveyor belt 60. The upper conveyor belt 60 transports or conveys the food product in the first direction from the inlet 100 of the upper conveyor belt 60 to an outlet or end 104 of the upper conveyor belt 60. A first chute or deflector 108 is positioned near the outlet 104 of the upper conveyor belt 60 to deflect or direct the food product from the outlet 104 of the upper conveyor belt 60 downward to an inlet 112 of the middle conveyor belt 58. The middle conveyor belt 58 transports or conveys the food product in a second direction (opposite to the first direction) from the inlet 112 of the middle conveyor belt 58 to an outlet or end 116 of the middle conveyor belt 58. A second chute or deflector 120 is positioned near the outlet 116 of the middle conveyor belt 58 to deflect or direct the food product from the outlet 116 of the middle conveyor belt 58 downward to the inlet 78 of the main conveyor belt 56. The main conveyor belt 56 then conveys the food product toward the outlet 82 of the main conveyor belt 56 in the manner described above in the previous example. This second example of cooking food product may be desired, for example, when the food product requires longer cooking times. The control member 94 may control the three conveyor belts 56, 58, 60 at various speeds to adjust the cooking time of the food products. The control member 94 may adjust the speeds of the conveyor belts 56, 58, 60 independently or the speeds of the belts 56, 58, 60 may be adjusted in unison (e.g., all belts have the same speed).

Referring now to FIGS. 1-5, 7 and 8, the cooking device 20 includes a plurality of cooking zones 124, 128, 132, 136. In the illustrated example, the cooking device 20 includes four cooking zones 124, 128, 132, 136. In other examples, the cooking device 20 is capable of including any number of cooking zones and all of such possibilities are intended to be within the spirit and scope of the present disclosure. One example of another cooking device 20B including a different quantity of cooking zones is illustrated in FIGS. 22-35 and will be described in greater detail below. Additionally, it should be understood that the shape and size of the cooking zones 124, 128, 132, 136 and the components of the cooking device 20 included in each of the cooking zones 124, 128, 132, 136 may vary greatly and any and all of such variations are intended to be within the spirit and scope of the present disclosure.

With continued reference to FIGS. 1-5, 7 and 8, in the illustrated example, the cooking zones 124, 128, 132, 136 are serially oriented in a longitudinal direction along the cooking device 20. In order to assist with describing the plurality of cooking zones 124, 128, 132, 136, the cooking zones 124, 128, 132, 136 will be referred to as the first cooking zone 124, the second cooking zone 128, the third cooking zone 132 and the fourth cooking zone 136. This manner of numerical labeling is not intended to be limiting upon the present disclosure. Additionally, this numerical allocation of the zone is not intended to imply a consecutive order of the cooking zones in either an upstream or downstream manner; however, in some examples, this numerical allocation may imply a consecutive order of the cooking zones.

As indicated above, the illustrated example of the cooking device 20 includes four cooking zones 124, 128, 132, 136. Accordingly, the cooking device 20 includes four fans 140, 144, 148, 152 and four heating elements 156, 160, 164, 168 with one fan and one heating element associated with each cooking zone. In one example, it should be understood that the cooking device 20 may include any number of cooking zones and, accordingly, may include any number of fans and any number of heating elements as long as the number of fans and the number of heating elements is equal to the number of cooking zones. In other words, the cooking device 20 includes a complementary number of fans, heating elements and cooking zones. In other examples, the cooking device 20 may include a different number of fans and/or cooking elements than the number of cooking zones.

Referring now to FIGS. 10 and 11, a cross-section of the fourth cooking zone 136 is illustrated. In the illustrated example of the fourth cooking zone 136, heated air 172 is directed over the food product in a horizontal or side-to-side manner. As indicated above, the illustrated example of the cooking device 20 includes three layers of conveyor belts 56, 58, 60, thereby defining a cooking location 176, 180, 184 on each of the three conveyor belts 56, 58, 60 (three cooking locations). The heated air 172 is directed horizontally through each of the cooking locations 176, 180, 184 defined above each of the conveyor belts 56, 58, 60. In order to facilitate this horizontal flow of heated air 172 over the food product in all three cooking locations 176, 180, 184 within all of the cooking zones 124, 128, 132, 136, each cooking zone includes a fan 140, 144, 148, 152, a heating element 156, 160, 164, 168, an air infeed chamber or path 188, 192, 196, 200, and an air return chamber or path 204, 208, 212, 216. In the illustrated example of the fourth cooking zone 136, the fan 152 and heating element 168 are positioned above the conveyor belts 56, 58, 60. In the fourth cooking zone 136, the fan 152 draws return air 224 (or air that is exiting the cooking locations) from the cooking locations 176, 180, 184 into a fan chamber 220 via the air return path 216. The fan 152 then directs return air 224 from the fan chamber 220, through the heating element 168 where the return air 224 is heated into heated air 172 and then directs the heated air 172 into the air infeed path 200. The air infeed path 200 is configured to direct the heated air 172 from the heating element 168 and direct the heated air 172 into the cooking locations 176, 180, 184 in a horizontal manner. The heated air 172 passes through the three cooking locations 176, 180, 184 in a horizontal manner and exits the three cooking locations 176, 180, 184 back into the air return path 216. The return air 224 is then drawn or directed back into the fan chamber 220 via the fan 152 where the return air 224 is again cycled through the zone 136.

With continued reference to FIGS. 10 and 11, the hood 40 assists with defining the air flow path around the fourth cooking zone 136. The hood 40 provides an upper limiting surface positioned above the fan 152, the fan chamber 220 and the heating element 168 to inhibit air from escaping the air flow path in an upward direction. The hood 40 also assists with defining the air infeed path 200 along with a first side plate 228 of the cooking device 20. Further, the hood 40 assists with defining the air return path 216 along with a second side plate 232 of the cooking device 20. In the illustrated example, a plurality of openings or apertures 236 are defined through the first side plate 228 in fluid communication with the air infeed path 200 and the three cooking locations 176, 180, 184. One opening 236 is aligned with each of the three cooking locations 176, 180, 184 to allow heated air 172 to pass through the first side plate 228 and enter the cooking locations 176, 180, 184 in a horizontal manner. In the illustrated example, the openings 236 are elongated slots having a longitudinal extent extending parallel to a longitudinal extent of the conveyor belts 56, 58, 60. In other examples, the openings 236 may have any shape and size and all of such possibilities are intended to be within the spirit and scope of the present disclosure. In other examples, any number of openings 236 may be defined in the first side plate 228 and in fluid communication with the air infeed path 200 and the three cooking locations 176, 180, 184. For example, the first side plate 228 may include a plurality of openings defined therein at each of the three cooking locations 176, 180, 184 to direct heated air 172 through a plurality of openings into each of the three cooking locations 176, 180, 184.

With continued reference to FIGS. 10 and 11, the illustrated example of the cooking device 20 includes adjustable openings 236 that are configured to be adjusted to change the size of the openings. Decreasing the size of the openings 236 increases the velocity of the heated air 172 passing through the openings 236 into the three cooking locations 176, 180, 184. Conversely, increasing the size of the openings 236 decreases the velocity of the heated air 172 passing through the openings 236 into the three cooking locations 176, 180, 184. The openings 236 may be adjustable in any manner and all of such possibilities are intended to be within the spirit and scope of the present disclosure.

In the illustrated example, each of the openings 236 is comprised of a nozzle 238 and each of the nozzles 238 includes a pair of converging members or plates 240, 244 having an inlet and an outlet with the outlet being smaller than the inlet. This nozzle configuration increases the velocity and/or flow rate of the heated air 172 as it passes from the air infeed path 200 into the cooking locations 176, 180, 184. It should be understood that the nozzles 238 may have any configuration and all of such possibilities are intended to be within the spirit and scope of the present disclosure. Returning to the illustrated example, the converging plates 240, 244 may be moved relative to each other to adjust the spacing between the two plates 240, 244. Moving the plates 240, 244 closer together will decrease the size of the opening 236 in the nozzle 238, thereby resulting in increasing the velocity of the heated air 172 exhausted from the nozzle 238. Conversely, moving the plates 240, 244 further apart will increase the size of the opening 236 in the nozzle 238, thereby resulting in decreasing the velocity of the heated air 172 exhausted from the nozzle 238. In one example, one of the plates 240 or 244 may be moveable and the other plate 240 or 244 may be fixed. In another example, both plates 240, 244 may be moveable. In one example, the openings 236 or nozzles 238 may be adjusted independently of each other. For example, with respect to FIG. 11, the bottom opening 236 or nozzle 238 has a smaller opening than the top and middle nozzle 238. In another example, all of the nozzles 238 may be adjusted together and have the same size opening. In the illustrated example, the openings 236 are adjusted vertically. That is, a height of each of the openings 236 is adjusted to be higher or lower. In other examples, the size of the openings 236 may be adjusted horizontally. That is, a width of each of the openings 236 may be adjusted to be wider or narrower.

In examples of the cooking device 20 where the openings 236 are adjustable, the openings 236 may be adjusted in a variety of manners. In one example, the openings 236 are adjustable manually. With respect to the illustrated example, if the openings 236 are adjusted manually, a person may manually loosen one or both of the plates 240, 244, move the one or both of the plates 240, 244 to a desired location, then secure the one or both of the plates 240, 244 in the desired location. This may be performed for any number of the openings 236. In another example, the openings 236 may be adjusted by a control member 94. In this example, the cooking device 20 may include one or more actuators and/or motors coupled to any number of the openings 236 to adjust the size of the openings 236. The actuators are in electronic communication with the control member 94 and the control member 94 may activate the actuator(s) to adjust the size of the openings 236. Adjusting the openings 236 with a control member 94 provides the ability to adjust the size of the openings 236 during cooking operation of the cooking device 20. Whereas, manually adjusting the openings 236 may require the cooking device 20 to adequately cool down after the cooking operation to provide a safe condition for a person adjusting the openings 236. In some examples, the control member 94 may independently adjust the openings 236, thereby proving the capability of having different sized openings 236, or the control member 94 may adjust the openings 236 in sync, thereby ensuring the openings 236 have the same size. In a further example, the openings 236 could be adjusted in sync within a similar zone. In still a further example, the openings 236 could be adjusted in sync on a level or tier basis. For example, all of the openings 236 on the bottom tier associated with the main conveyor belt 56 may be adjusted in sync with each other, all the openings 236 in the middle tier associated with the second or middle conveyor belt 58 may be adjusted in sync with each other, and all the openings 236 in the top tier associated with the top conveyor belt 60 may be adjusted in sync with each other. In yet other examples, the openings 236 may be fixed and non-adjustable. In such an example with fixed openings 236, desirable operability may occur with specific sizes of the openings 236 and such desirable operability may be ensured by fixing the size of the openings 236.

With further reference to FIGS. 10 and 11, the illustrated example of the cooking device 20 includes a plurality of openings or apertures 248 defined through the second side plate 232 in fluid communication with the three cooking locations 176, 180, 184 and the air return path 216. A pair of openings 248 are aligned with each of the three cooking locations 176, 180, 184 to allow heated air 172 to pass through the second side plate 232 and exit the cooking locations 176, 180, 184 in a horizontal manner into the air return path 216. In the illustrated example, the openings 248 are elongated slots having a longitudinal extent extending parallel to a longitudinal extent of the conveyor belts 56, 58, 60. In other examples, the openings 248 may have any shape and size and all of such possibilities are intended to be within the spirit and scope of the present disclosure. In other examples, any number of openings 248 may be defined in the second side plate 232 and in fluid communication with the three cooking locations 176, 180, 184 and the air return path 216. For example, the second side plate 232 may include a single opening 248 defined therein at each of the three cooking locations 176, 180, 184 or more than two openings 248 at each of the three cooking locations 176, 180, 184 to allow air to exit the cooking locations 176, 180, 184 and enter the air return path 216.

With continued reference to FIGS. 10 and 11, the illustrated example of the openings 248 defined in the second side plate 232 are fixed in size and shape. In other examples, the openings 248 defined in the second side plate 232 may be adjustable to adjust the size of the openings 248. In such an example, the openings 248 defined in the second side plate 232 may have any configuration, operation and alternatives describe with respect to the openings 236 defined in the first side plate 228 or they may have different configurations and operations, with all of such possibilities intended to be within the spirit and scope of the present disclosure.

In one example, one or more of the first and second side plates 228, 232 may be movable to selectively expose and cover the components of the cooking device 20 behind the side plates 228, 232. This movability may allow a user to clean and/or repair/replace the components of the cooking device 20 behind the side plates 228, 232.

With reference to FIGS. 20 and 21, in one example, one or more of the first and second side plates 228, 232 may be comprised of two plates 340 with each plate 340 being pivotable or rotatable about one or more hinges 344 or other mechanisms allowing the one or more side plates 228, 232 to pivot or rotate relative to the cooking device 20 between an opened position (see FIG. 21; only one door shown in the opened position) and a closed or secured position (see FIG. 20; both doors shown in the closed position). One or more securing or locking mechanism 348 such as, for example, clasps, friction-fit mechanisms, interference-fit mechanisms, detents, latches, or other securing or locking mechanisms may be used with the pivotable or rotatable side plates 228, 232 to secure the side plates 228, 232 in the closed or secured position. In one example, the first and second side plates 228, 232 may be comprised of a single plate each (rather than two plates each as illustrated in FIGS. 20 and 21) and the single plate may be pivotable or rotatable about one or more hinges or other mechanisms.

In another example, one or more of the first and second side plates 228, 232 may be removable from the cooking device 20. The cooking device 20 may include any type of coupling mechanism that allows the removable side plates 228, 232 to be selectively coupled to and removed from the cooking device 20. In a further example, one or more of the first and second plates 228, 232 may be both pivotable and removable.

Referring now to FIGS. 12 and 13, a cross-section of the third cooking zone 132 is illustrated. In the illustrated example of the third cooking zone 132, heated air 172 is directed over the food product in a horizontal or side-to-side manner similarly to the fourth cooking zone 136. In the illustrated example, heated air 172 is directed over the food product in a horizontal manner in all of the cooking zones 124, 128, 132, 136. The third cooking zone 132 is similar to the fourth cooking zone 136 described in detail above except, for example, the position of the fan 148 and heating element 164 are reversed and the horizontal air flow over the food product is in an opposite horizontal direction to the direction of the air flow in the fourth cooking zone 136. More particularly, the fan 148 and heating element 164 in the third cooking zone 132 are still positioned above the conveyor belts 56, 58, 60, but the fan 148 in the third cooking zone 132 is on the same side of the cooking device 20 as the heating element 168 in the fourth cooking zone 136. Similarly, the heating element 164 in the third cooking zone 132 is on the same side of the cooking device 20 as the fan 152 in the fourth cooking zone 136. The air flow in the third cooking zone 132 is reversed relative to the air flow in the fourth cooking zone 136. That is, as viewed in the cross-sectional views illustrated in FIGS. 10 and 12, the air flow in the fourth cooking zone 136 illustrated in FIG. 10 circulates through the fourth cooking zone 136 in a counter-clockwise direction and the air flow in the third cooking zone 132 illustrated in FIG. 12 circulates through the third cooking zone 132 in clockwise direction. The third cooking zone 132 includes similar structure as the fourth cooking zone 136, but the positioning of at least some of the structure in the third cooking zone 132 is reversed or on opposite sides of the cooking device 20 than the structure of the fourth cooking zone 136.

Referring now to FIGS. 10 and 11, as previously described, the illustrated example of the cooking device 20 includes four cooking zones 124, 128, 132, 136. In the illustrated example, the heated air 172 is horizontally directed over the food product in the cooking locations 176, 180, 184 of all of the cooking zones 124, 128, 132, 136. Additionally, in the illustrated example, the heated air 172 is directed through the cooking locations 176, 180, 184 in alternating horizontal directions. For example, the heated air 172 is directed in a first horizontal direction 252 in the first cooking zone 124, the heated air 172 is directed in a second horizontal direction 256 opposite to the first horizontal direction 252 in the second cooking zone 128, the heated air 172 is directed in the first horizontal direction 252 in the third cooking zone 132 and the heated air 172 is directed in the second horizontal direction in the fourth cooking zone 136. Accordingly, in the illustrated example, the heated air 172 is directed through the cooking locations 176, 180, 184 in the same horizontal direction in the first and third cooking zones 124, 132 and the heated air 172 is directed through the cooking locations 176, 180, 184 in the same horizontal direction in the second and fourth cooking zones 128, 136. As indicated above, the cooking device 20 is capable of having any number of cooking zones and, accordingly, the heated air 172 may be alternatively directed throughout any number of cooking zones included in the cooking device 20. Horizontal directing of the heated air 172 may also be considered as being directed in a direction generally parallel to top surfaces of the conveyor belts 56, 58, 60.

In other examples, the cooking device 20 may direct the heated air 172 over the food product through the cooking locations 176, 180, 184 in other manners. For example, heated air 172 may be horizontally directed over the food product in the cooking locations 176, 180, 184 in a first direction in any number of the cooking zones and heated air 172 may be horizontally directed over the food product in the cooking locations 176, 180, 184 in a second direction opposite the first direction in any number of the other cooking zones not having heated air directed therethrough in the first direction.

The cooking device 20 is configured to substantially isolate the cooking zones 124, 128, 132, 136 from one another to ensure consistent and reliable cooking conditions within each cooking zone. Additionally, in some examples, the cooking conditions within each of the cooking zones 124, 128, 132, 136 is independently controlled to provide a desired manner of cooking the food product. Examples of the components with the cooking zones 124, 128, 132, 136 that may be independently controlled include, but are not limited to, the fan 140, 144, 148, 152, the heating element 156, 160, 164, 168, the size of the openings 236 in the first and/or second side plates 228, 232 and a humidity within each cooking zone 124, 128, 132, 136 via one or more humidifying elements 260 (the cooking device 20 may include a single humidifying element within the cooking device 20 or any number of humidifying elements throughout the cooking device 20). In one example, the cooking device 20 may control the humidity for the entire cooking device 20 rather than controlling the humidity for each cooking zone 124, 128, 132, 136. In one example, the cooking device 20 includes a plurality of pipes for transporting steam to the humidifying elements 260 within the cooking device 20. In such an example, the pipes may all be the same length from a steam source or neck where the individual pipes separate to extend to their associated humidifying elements 260. By having similar length pipes, a substantially equal quantity of steam may be transported to all of the humidifying elements 260. Further, in such an example, the cooking device 20 may include a single valve to control the flow of steam to the humidifying elements 260. In another example, each pipe or each humidifying element 260 may include its own valve to individually control the quantity of steam transported to the humidifying elements. 260.

With continued reference to FIGS. 10 and 11, the cooking device 20 includes a plurality of guide members 262 to assist with guiding the food product through the cooking device 20. In the illustrated example, the guide members 262 are positioned near each edge of the transport devices 56, 58, 60 to inhibit food product from falling off the sides of the transport devices 56, 58, 60. In other examples, the cooking device 20 may include any number of guide members associated with any number of transport devices 56, 58, 60. Also, in the illustrated example, the guide members 262 are positioned underneath the nozzles 238 or, when considered in another manner, the nozzles 238 are positioned above the guide members 262. The guide members 262 may either be part of the side plates 228, 232 or may be independent components separate from the side plates 228, 232 and coupled within the cooking device 20.

With reference to FIGS. 14-16, the cooking device 20 includes a plurality of sealing members or engagement members 264 positioned between the first side plate 228 and an inner surface 268 of the hood 40 and a plurality of engagement members 264 positioned between the second side plate 232 and the inner surface 268 of the hood 40. In the illustrated example, each cooking zone 124, 128, 132, 136 includes four engagement members 264, with two engagement members 264 extending from the first side plate 228 and two engagement members 264 extending from the second side plate 232. Each cooking zone 124, 128, 132, 136 includes two of the engagement members 264 near an inlet end of the cooking zone (inlet end of a cooking zone may be determined as the end of cooking zone nearest the inlet of the main conveyor belt) and two of the engagement members 264 near an outlet end of the cooking zone (outlet end of a cooking zone may be determined as the end of the cooking zone nearest the outlet of the main conveyor belt).

When the hood 40 is in the downward position, the inner surface 268 of the hood 40 engages the engagement members 264 to form both the air infeed path 188, 192, 196, 200 and the air return path 204, 208, 212, 216. Once the hood 40 engages the engagement members 264, the air infeed path 188, 192, 196, 200 is defined by the inner surface 268 of the hood 40 on an outside of the path, engagement members 264 on the ends of the path and the first side plate 228 on an inside of the air infeed path. The air return path 204, 208, 212, 216 is defined by the inner surface 268 of the hood 40 on an outside of the path, engagement members 264 on the ends of the path and the second side plate 232 on an inside of the air return path.

In the illustrated example, the engagement members 264 have a tapered shape that taper from a wide end 272 at a bottom of the engagement members 264 to a narrower end 276 at a top of the engagement members 264. This tapered shape provides a ramped or angled surface 280 on each of the engagement members 264 that mate or engage a complementary ramped or angled surface 284 on the interior surface 268 of the hood 40. These ramped surfaces 280, 284 may facilitate proper downward guiding and alignment of the inner surface 268 of the hood 40 relative to the remainder of the cooking device 20, gradual engagement between the inner surface 268 of the hood 40 and/or a proper seal between the inner surface 268 of the hood 40 and the engagement members 264 to properly seal and/or substantially isolate the cooking zones 124, 128, 132, 136 relative to one another. Upon full engagement between the inner surface 268 of the hood 40 and the engagement members 264, little to no air may pass between the engagement members 264 and the inner surface 268 of the hood 40 engaging the engagement members 264.

Engagement members 264 positioned at the extreme ends of the cooking device 20 (e.g., at the infeed end of the first cooking zone 124 and at the outfeed end of the fourth cooking zone 136) inhibit air from escaping ends of the first and fourth cooking zones 124, 136 and into the atmosphere. Engagement members 264 positioned between cooking zones 124, 128, 132, 136 internally of the extreme ends of the cooking device 20 inhibit air from passing from one cooking zone to an adjacent cooking zone.

The cooking device 20 is also capable of relatively isolating the cooking zones 124, 128, 132, 136 by circulating air through the cooking zones at a sufficiently high velocity. The cooking zones 124, 128, 132, 136 are in fluid communication at the cooking locations 176, 180, 184 above each of the three conveyor belts 56, 58, 60. Circulating the air in opposite directions at a sufficiently high velocity in adjacent cooking zones 124, 128, 132, 136 inhibits the air from wanting to flow into an adjacent zone at the cooking locations 176, 180, 184. The velocity of the air flow may be a wide variety of air flows and be sufficiently high to inhibit air flow between adjacent cooking zones 124, 128, 132, 136 at the cooking locations 176, 180, 184 above the conveyor belts 56, 58, 60. For example, the velocity of the air may be between about 0 meters/second (m/s) and about 20 m/s. Also, for example, the velocity of the air may be between about 0 m/s and about 10 m/s.

Referring now to FIGS. 1-3 and 13, the cooking device 20 includes a thermal seal 281 between the hood 40 and the base 48. The thermal seal 281 is configured to inhibit air from undesirably escaping from an interior of the cooking device 20 between the hood 40 and the base 48. The cooking device 20 may include a wide variety of thermal seals and all of such possibilities are intended to be within the spirit and scope of the present disclosure. In the illustrated example, the thermal seal 281 includes a basin or receptacle 282 on two sides of the base 48 both of which are configured to contain a liquid such as, for example, water. Portion or bottom edges 283 of the hood 40 are submerged within the liquid contained within the receptacles 282, thereby creating a thermal seal between the hood 40 and the base 48.

The cooking device 20 disclosed herein is configured to provide a more controlled and uniform environment therein. The environment is comprised of air flow, temperature and humidity. The cooking device 20 provides significant control of these characteristics. For example, cooking device 20 is separated into a plurality of zones. Smaller, divided zones within the cooking device and independent control thereof provide smaller environments which are easier to control than one larger environment. Additionally, with respect to independent control of each cooking zone, the fan, the air return and the air discharge are positioned within each cooking zone in a manner that limits air turbulence and controls the air throughout the coking zone in a more effective manner. The positioning of the components within each cooking zone and the independent control of each cooking zone facilitate more uniform temperature in the cooking locations of the cooking zones. Whereas, in conventional cooking devices, such conventional cooking devices may have a single large cooking cavity and blow heated air into the large cooking cavity from a top of the cooking cavity. In such a large cooking cavity, the air is free to move around in the cavity in a turbulent and uncontrolled/natural manner, which results in non-uniform temperatures within the large cooking cavity. Non-uniform temperatures result in unpredictable and/or unreliable cooking operation of the food product.

Referring now to FIGS. 5, 17 and 18, the illustrated example of the cooking device 20 includes a cleaning device 288 capable of cleaning the main conveyor belt 56. The main conveyor belt 56 wraps around various rollers 72 and is oriented between a pair of brushes 292. The brushes 292 are configured to engage the main conveyor belt 56 and brush or engage the main conveyor belt 56 to loosen or dislodge debris that is positioned on the main conveyor belt 56. The brushes 292 can have a variety of configurations and can be made of a variety of materials. For example, the brushes 292 may include a flat circumference, a plurality of projections or nodules extending outward from the circumference, a plurality of bristles, or any other configuration. Additionally, for example, the brushes 292 (including their circumference, projections, nodules, bristles, etc.) may be made out of a wide variety of materials including stainless steel, plastic, rubber, metal, composite materials, or any other material. In other examples, the cooking device 20 includes a single brush 292. In still other examples, the cooking device 20 includes any number of brushes 292 and all of such possibilities are intended to be within the spirit and scope of the present disclosure.

In the illustrated example, the main conveyor belt 56 passes between the pair of brushes 292. The first or top brush 292 engages a first surface 296 of the main conveyor belt 56 and the second or bottom brush 292 engages a second surface 300 of the main conveyor belt 56 opposite the first surface 296. In one example, the brushes 292 may be driven or rotated by a motor or other actuation device. In other examples, the brushes 292 may be passive and unpowered, whereby movement of the main conveyor belt 56 past the brushes 292 causes the brushes 292 to rotate. Returning to the illustrated example, the brushes 292 extend at least the width of the main conveyor belt 56 and in some cases wider than the main conveyor belt 56 to ensure the entire width of the main conveyor belt 56 is engaged by the brushes 292.

A plurality of sprayers 304 capable of spraying a fluid onto the main conveyor belt 56 are orientated adjacent to or near the main conveyor belt 56. In the illustrated example, the sprayers 304 are oriented downstream of the brushes 292 (downstream established based on the direction of movement of the main conveyor belt 56—in other words, the main conveyor belt 56 passes by the brushes prior to the sprayers 304). In this example, the sprayers 304 spray fluid onto the main conveyor belt 56 to loosen and/or dislodge debris that is on the main conveyor belt 56. By having the sprayers 304 downstream of the brushes 292, the brushes 292 may initially loosen and/or dislodge debris and the sprayers 304 will subsequently spray fluid onto the main conveyor belt 56 to remove the debris from the main conveyor belt 56. In one example, the sprayers 304 spray water. In another example, the sprayers 304 spray air. In a further example, the sprayers 304 may spray a mixture of water and cleaning solution or soap.

Returning to the illustrated example, the sprayers 304 extend at least the width of the main conveyor belt 56 and in some cases wider than the main conveyor belt 56 to ensure the entire width of the main conveyor belt 56 is sprayed by the sprayers 304. In other examples, the sprayers 304 may not extend the entire width of the main conveyor belt 56, but are capable of spraying the entire width of the main conveyor belt 56. In the illustrated example, the sprayers 304 are disposed below the main conveyor belt 56 or disposed below a nip 308 between the two brushes 292 through which the main conveyor belt 56 passes. The sprayers 304 spray the fluid upward toward the main conveyor belt 56. The sprayers 304 may also be generally directed toward the nip 308 between the two brushes 292. In another example, the sprayers 304 may be disposed above the main conveyor belt 56 or disposed above the nip 308. In such an example, the sprayers 304 would spray fluid downward toward the main conveyor belt 56. In this example, the sprayers 304 may also be directed toward the nip 308. In other examples, the cooking device 20 may include any number of sprayers arranged in any number of rows of sprayers or any other configuration. For example, some sprayers may be disposed above the main conveyor belt 56 and other sprayers may be disposed below the main conveyor belt 56.

The brushes 292 and sprayers 304 are disposed over a waste bin or container 312 which is configured to receive the sprayed fluid and any debris dislodged from the main conveyor belt 56. A drain 316 is positioned in a bottom of the waste bin 312 to evacuate the fluid and debris from the waste bin 312. In one example, the waste bin 312 is continuously drained under gravity. In another example, the cooking device 20 may include a pump to assist with draining the contents out of the waste bin 312. In one example, a sensor 320 (see FIG. 36) may be positioned in the waste bin 312 to sense a height of fluid accumulating in the waste bin 312. If the fluid level is too high and activates the sensor 320, the sensor 320 will send data to the control member 94 of the cooking device 20 to indicate a high fluid level in the waste bin 312. The control member 94 may react in a variety of manners. In one example, the control member 94 may shutdown the cooking device 20. In another example, the control member 94 may activate one or more of a visual indicator 324 (e.g., an illumination device such as a light, LED, display an item on a monitor or display, etc.) and an audible indicator 328 (e.g., such as an audible alarm, bell, speaker, etc.). In a further example, the control member 94 may send data or a communication to a server, database or other electronic device where the data will be stored and/or acted upon by at least one of a person or an electronic device. In still a further example, the control member 94 may shutdown the cleaning device 288. In such an example, the cleaning device 288 may include one or more valves 350 to selectively interrupt the flow of water to the cleaning device 288 and/or may interrupt power to the cleaning device 20.

Referring now to FIGS. 22-35, another example of a cooking device 20B is illustrated. The cooking device 20B includes many similarities to the cooking devices illustrated in FIGS. 1-21 and 36, and all of such similarities may be identified with like reference numbers and a “B”. At least some of the differences between the cooking device 20B and the other cooking devices illustrated in FIGS. 1-21 and 36 will be described herein. It should be understood that the cooking device 20B is capable of having any of the structure, functionality and other examples or alternatives of the other cooking devices described herein in any combination. Accordingly, for the sake of brevity, it is not necessary to repeat each and every possible example and alternative associated with each component and functionality of the cooking device 20B. All of such possibilities are intended to be with in the spirit and scope of the present disclosure. It should further be understood that reference to one or more possible other examples or alternatives associated with the cooking device 20B or a lack of addressing other possible examples or alternatives for the sake of brevity is not intended to be limiting upon the present disclosure.

As indicated above, the cooking devices disclosed herein are capable of including any number of cooking zones and all of such possibilities are intended to be within the spirit and scope of the present disclosure. With particular reference to FIGS. 22-25, in the illustrated example, the cooking device 20B includes six cooking zones 124B, 128B, 132B, 136B, 400, 404. In the illustrated example, air flow through the cooking zones are represented by arrows 408. Similarly to the other cooking devices disclosed herein, the airflow in the cooking device 20B flows in alternating directions from zone to zone. Particular reference is made to FIG. 23 for examples of the airflow directions through the plurality of cooking zones. In the illustrated example, the cooking zones are designed to have substantially similar structure and function. By having the cooking zones substantially similar, the cooking zones have more uniform operation and equal behavior, thereby making it easier to add or subtract cooking zones to or from the cooking device 20B as desired. For example, with reference to FIG. 23, the zones are all shown as having the same length or same dimension W in the longitudinal direction of the cooking device 20B. It should also be understood that, in some examples, the cooking zones may also have the same width/depth and same height as each other so that all three dimensions of all the zones are the same.

It should be understood that the cooking device 20B is capable of having all the other examples and alternatives described above with respect to airflow therethrough. Additionally, in some examples, it should be understood that the shape and size of the cooking zones and the components of the cooking device 20B included in each of the cooking zones may vary greatly and any and all of such variations are intended to be within the spirit and scope of the present disclosure.

Referring now to FIGS. 26 and 27, the cooking device 20B includes one example of a plurality of sealing members or zone dividing members 412. The zone dividing members 412 are configured to assist with separating the cooking zones from one another and, for example, separate the environments within the cooking zones from one another. For example, as described above, it may be desirable to independently control the environment within each of the plurality of cooking zones. The zone dividing members 412 assist with separating these environments and make it easier to control these environments.

In the illustrated examples, the zone dividing members 412 extend downward from a top, inner surface 268B of the hood 40B and engage a surface 416 within the cooking device 20B. In the illustrated example, the zone dividing members 412 are positioned at the ends of the cooking device 20B (near the inlet and outlet of the cooking device 20B) to assist with defining the two end cooking zones, and positioned between the cooking zones. The zone dividing members 412 are capable of having a wide variety of shapes, sizes and configurations. In some examples, the zone dividing members 412 may all have a similar size, shape and configuration. In other examples, including the illustrated example, the zone dividing members 412 may have different shapes relative to each other.

With continued reference to FIGS. 26 and 27, the zone dividing members 412 near the inlet and outlet of the cooking device 20B are substantially straight and vertical. Proceeding inward from these zone dividing members 412 toward a longitudinal center 420 of the cooking device 20B, the next zone dividing members 412 are not substantially straight (e.g., could be considered zig-zag shaped). Continuing to proceed inward toward the longitudinal center 420 of the cooking device 20B, the next zone dividing members 412 are straight and a centrally located zone dividing member 412 is not straight (e.g., could be considered zig-zag shaped). Accordingly, in the illustrated example, the zone dividing members 412 alternate from straight to non-straight from one end of the cooking device 20B to the other end. In one example, the zone dividing members 412 alternate in shape in order to accommodate the orientation of the components within each cooking zone. For example, the orientation of at least one of the fan, air chambers, etc., within the cooking zones requires a non-straight zone dividing member 412 on one end of each cooking zone and a straight zone dividing member 412 on the other end of each cooking zone. Also, in the illustrated example, at least some of the zone dividing members 412 may include an aperture, slot or cutout 424 therein for allowing other components of the cooking device 20B to pass therethrough or thereby. In the illustrated example, the non-straight zone dividing members 412 include a slot 424 therein to allow components associated with the humidifying and/or cleaning capabilities of the cooking device 20B.

With additional reference to FIGS. 26 and 27, each zone dividing member 412 includes a rigid portion 428 and a flexible portion 432 extending from a bottom edge 436 of the rigid portion 428. The flexible portion 432 of each of the zone dividing members 412 is configured to engage the surface 416 within the cooking device 20B, thereby causing the flexible portion 432 to flex relative to the rigid portion 428 and the surface 416 within the cooking device 20B. The flexible portion 432 of each zone dividing member 412 provides a seal between the zone dividing members 412 and the surface 416 within the cooking device 20B, and allows for tolerances or variations that may occur within the cooking device 20B that may not be able to be facilitated by completely rigid zone dividing members.

Referring now to FIGS. 28 and 29, at least some of the side plates 228B, 232B of the cooking device 20B include a flange 440 to assist with controlling the environment within each of the cooking zones. More particularly, the flanges 440 are configured to assist with defining air paths within the cooking zones to inhibit air from undesirably escaping the air paths. In the illustrated example, the side plates 228B, 232B that at least partially define the air return paths of the cooking zones include the flange 440. In one example, these flanges 440 engage a portion 444 of the inner surface 268B of the hood 40B to inhibit air from escaping the return air paths between the hood 40B and a portion of the cooking device 20B. These flanges 440 substantially close-off or seal gaps 448 between the inner surface of the hood 268B and a portion of the cooking device 20B associated with the cooking zones (see FIG. 29). In the illustrated example, the flanges 440 are angled downward relative to a horizontal plane. In other examples, the flanges 440 may have any shape, size and configuration and all of such possibilities are intended to be within the spirit and scope of the present disclosure. In one example, the flanges 440 engage the inner surface 268B of the hood 40B in the gaps 448. In other examples, the flanges 440 do not engage the inner surface 268B of the hood in the gaps 448, but still substantially close off or seal the gaps 448.

As indicated above, it should be understood that each cooking zone may include a single side plate 228B, 232B or a pair of sides plates at the sides of the cooking zones. In the illustrated example, each side plate 228B, 232B is comprised of a pair of side plates that pivot or rotate (similar to the pair of side plates 340 described above). In this illustrated example, the flange 440 is comprised of a pair of flanges 440A, 440B with one flange extending from a top and the length of a respective one of the two side plates. In other examples that include a single side plate 228B, 232B at the sides of each cooking zone, the flange 440 is a single flange 440 extending from a top and along the length of the single side plate 228B, 232B.

With reference to FIGS. 30 and 31, one example of the plurality of transport members or conveyor belts 56B, 58B, 60B of the cooking device 20B is illustrated. In this example, the plurality of transport members 56B, 58B, 60B are positioned more closely together in a vertical manner (see dimension X) than in other cooking devices disclosed herein (see, for example, dimension Z in FIG. 5). By decreasing the overall vertical distance between transport members 56B, 58B, 60B, the overall height of the cooking device 20B may be decreased, thereby providing efficiencies. Moreover, by having a lower overall height of the cooking device 20B, the height provided by the hood 40B when lifted upward by the lifting mechanisms 44B will also be lower. Decreasing the overall height of the hood 40B when lifted upward will allow the cooking device 20B to be used in more environments and/or facilities with limited overhead space. Also, for example, the overall height of the cooking zones is reduced, thereby providing less space or environment within the cooking zones to control. That is, environments within smaller spaces may be easier to control than environments within larger spaces. As a result of more easily controlled spaces and environments, the cooking device 20B requires less energy and/or resources to operate the cooking device 20B in a desired manner. Accordingly, the cooking device 20B is more efficient and may be less expensive to operate.

Referring now to FIGS. 32 and 33, the cooking device 20B includes one example of a plurality of drip pans 450. In the illustrated example, the cooking device 20B includes four drip pans 450 in each cooking zone. In each cooking zone, two of the drip pans 450 are positioned underneath the upper conveyor belt 60B and two drip pans 450 are positioned under the middle conveyor belt 58B. The drip pans 450 positioned under the upper conveyor belt 60B are configured to catch grease, food product, portions of food product, or any other debris that falls from the upper conveyor belt 60B. Similarly, the drip pans 450 positioned under the middle conveyor belt 58B are configured to catch grease, food product, portions of food product, or any other debris that falls from the middle conveyor belt 58B. In other examples, the cooking device 20B may include any number of drip pans 450 in each cooking zone and all of such possibilities are intended to be within the spirit and scope of the present disclosure. For example, the cooking device 20B may alternatively include a single drip pan under the upper conveyor belt 60B and a single drip pan under the middle conveyor belt 58B in each zone. In other examples, each cooking zone of the cooking device 20B may include more than two drip pans.

With particular reference to FIG. 32, in the illustrated example, the plurality of drip pans 450 are substantially identical in shape, size and configuration. In other examples, the drip pans 450 may have different shapes, sizes and configurations relative to each other and all of such possibilities are intended to be within the spirit and scope of the present disclosure.

Referring now to FIG. 33, a pair of the plurality of drip pans 450 are illustrated and will be described herein. The drip pans 450 are substantially identical in configuration and functionality, and it should be understood that the following description applies to all of the drip pans 450 included in the cooking device 20B. Each drip pan 450 includes a plurality of vertical walls 452 extending upward from a base or floor 454 of the drip pan 450 and a drain 456. In the illustrated example, the drain 456 is positioned in or near a corner of the drip pan 450, and the floor 454, in the illustrated example, is angled in two directions or manners relative to horizontal toward the drain 456. More particularly, with respect to the drip pan 450 illustrated on the left in FIG. 33, the floor 454 of the drip pan 450 angles, as viewed in FIG. 33 downward from right to left (represented by arrows 451) and from the rear to the front (represented by arrows 453), with both directions being toward the drain 456. Accordingly, grease or debris falling onto the drip pan 450 will flow or move under the force of gravity toward the drain 456. Any such grease and/or debris may then pass through the drain 456 and exhausts or exit from the drip pan 450 as represented by arrows 457.

Referring again to FIG. 32, the two drip pans 450 on the left (as viewed in FIG. 32) are positioned in the cooking device 20B in a first orientation and the two drip pans 450 on the right are positioned in the cooking device 20B in a second orientation. In the illustrated example, the two drip pans 450 on the right are positioned in the cooking device 20B at about a 180-degree rotated position relative to the drip pans 450 on the left. Thus, the drains 456 for the drip pans 450 on the left are positioned on one side of the cooking device 20B (the near side as viewed in FIG. 32) and the drains 456 for the drip pans 450 on the right are positioned on an opposite side of the cooking device 20B (the far side as viewed in FIG. 32). Additionally, in the illustrated example, the drains 456 of the upper drip pans 450 are substantially vertically aligned with the drains 456 of the lower drip pans 450 such that any grease, debris, etc., exhausted or dripping from the drains 456 of the upper drip pans 450 falls into the drains 456 of the respective lower drip pans 450.

With reference to FIGS. 32 and 33, in the illustrated example, the plurality of drip pans 450 are selectively couplable and removable from the cooking device 20B in order to facilitate cleaning, replacement and/or repair of the drip pans 450. In the illustrated example, the cooking device 20B includes a plurality of support members 458 configured to support the drip pans 450 within the cooking device 20B. The support members 458 are positioned within the cooking device 20B to support two, opposite sides 460 of each drip pan 450. In other examples, the plurality of drip pans 450 may be supported on any number of sides or supported within the cooking device 20B in any manner. In the illustrated example, the support members 458 include one or more generally L-shaped edge(s) 462 that is/are complementarily shaped to a corresponding edge or sides 460 of the drip pans 450. The drip pans 450 rest or are supported on the L-shaped edges 462 of the support members 458. This type of support or coupling of the drip pans 450 to the cooking device 20B provides vertical support to the drip pans 450 to inhibit the drip pans 450 from falling downward in the cooking device 20B, but allow horizontal sliding of the drip pans 450 relative to the cooking device 20B to enable the drip pans 450 to be removed from and inserted into the cooking device 20B. It should be understood that the drip pans 450 may be supported in or coupled to the cooking device 20B in a wide variety of manners and all of such manners are intended to be within the spirit and scope of the present disclosure.

With continued reference to FIG. 32, the drip pans 450 also act as air guiding plates to assist with guiding air in a desired manner through the cooking zones. In this manner, the drip pans/air guiding plates 450 are dual functional members. In the illustrated example, the drip pans/air guiding plates 450 are positioned in the lower and middle cooking areas 176B, 180B to assist with directing air in the lower and middling cooking areas 176B, 180B. The drip pans/air guiding plates 450 provide a ceiling or upper limit to the lower and middle cooking areas 176B, 180B to inhibit heated air from escaping the lower and middle cooking areas 176B, 180B through a top thereof. In this way, heated air remains in the lower and middle cooking areas 176B, 180B to heat the food product passing therethrough. Furthermore, the drip pans/air guiding plates 450 assist with providing optimal air speeds and/or reduce air turbulence in the cooking areas 176B, 180B.

With reference to FIG. 34, the cooking device 20B is shown with a plurality of nozzles 238B oriented just above or very close (see dimension Y) to a top surface 464 of each of the conveyor belts 56B, 58B, 60B. The nozzles 238B are oriented to blow or exhaust heated air very close to the top surface 464 of the conveyor belts 56B, 58B, 60B and at the level of the food product being transported through the cooking device 20B on the conveyor belts 56B, 58B, 60B rather than at a level above the food product. In the illustrated example, the cooking device 20B does not include guide members at edges of the conveyor belts 56B, 58B, 60B (see FIG. 7 associated with cooking device 20 for guide members 262). The presence of guide members may prohibit the nozzles 238B from being positioned close or adjacent to the top surfaces 464 of the transport members 56B, 58B, 60B and at the level of the food product. By removing or not including the guide members, the nozzles 238B can be positioned lower in the cooking areas 176B, 180B, 184B.

With reference to FIGS. 34 and 35, one example of a side plate 228B or 232B is illustrated and includes a plurality of nozzles 238B. In the illustrated example, each nozzle 238B includes a pair of converging plates 240B, 244B having an inlet and an outlet with the outlet of the nozzle 238B being smaller than the inlet. This nozzle 238B configuration increases the velocity and/or flow rate of the heated air as it passes from the air infeed path 200B into the cooking locations 176B, 180B, 184B. It should be understood that the nozzles 238B may have any configuration and all of such possibilities are intended to be within the spirit and scope of the present disclosure. Returning to the illustrated example, the nozzles 238B may be adjustable to adjust the spacing between the two plates 240B, 244B, thereby effecting the airflow in a manner described above with respect to the cooking device 20. In the illustrated example, the upper plate 240B is moveable and the lower plate 244B is fixed and a rigid part of the side plate 228B, 232B. In the illustrated example, the upper plate 240B is adjusted vertically. That is, a height of each of the openings 236B is adjusted to be higher or lower by moving the upper plate 240B. Each upper plate 240B includes a vertical portion 466 and an angled portion 468. The vertical portion 466 defines a pair of slots 470 therein configured to each receive a projection 472 therein. The slots 470 and projections 472 cooperate to facilitate vertical sliding of the upper plate 240B relative to the side plate 228B, 232B and inhibit horizontal movement of the upper plate 240B relative to the side plate 228B, 232B. The projections 472 may be threaded members such as, for example, bolts, and complementary threaded members, such as, for example, nuts, may cooperate with the projections 472 to selective secure or couple the upper plate 240B in place relative to the side plate 228B, 232B. The angled portion 468 extends from the vertical portion 466 at an obtuse angle into the cooking locations 176B, 180B, 184B to direct heated air into the cooking locations 176B, 180B, 184B. As can be seen in FIG. 34, the lower plate 244B of the nozzle 238B is extremely close or adjacent to the top surface 464 of the conveyor belts 56B, 58B, 60B (see dimension Y). In the illustrated example, the cooking device 20B does not include product guiding. However, with the nozzles 238B positioned in close proximity to the top surfaces 464 of the conveyor belts 56B, 58B, 60B, the nozzles 238B themselves may act as guiding members since any food product approaching edges of the conveyor belts 56B, 58B, 60B would engage the nozzles 238B and be biased away from the edges of the conveyor belts 56B, 58B, 60B by the nozzles 238B.

Referring now to FIG. 36, one example of a block diagram associated with one example of a cooking device 20C is illustrated. The block diagram is not intended to be limiting upon any of the cooking devices disclosed herein, but is rather provided to demonstrate at least some of the principles of the present disclosure. At least some of the components included in this exemplary block diagram have been introduced and described above in detail.
